How high should my humidity be and is it important? First time growing photos and all new equipment. Here is what I’m working with.
Welcome to The Forum this is a great place to learn. And yes humidity does matter to a certain extent. There are Growers here who can give you everything you need to know about the humidity but not me LOL I’m a pretty novice indoor grower myself I’ve only been doing it for a little over a year. But stick around you will get the info you need and hope to see you here for a while. Peace and happy growing
@brucealmighty To awnser your question yes humidity plays a large role in how your plants breath and move nutrients from the soil to were they need to go. Also to high a humidity makes for an unhealthy environment for your plants. The stage your plants are in 40 to 60% should work. I am sure someone will link you to were the subject is discussed in deapth.
@brucealmighty humidity is important as the wrong humidity at certain stages can stunt growth, cause nutrient issues, root issues, and mold issues.
During seedling stage 70-90% humidity is needed for proper development because seedlings don’t have a lot of roots so they get most of their water via the stomata and drink it from the air. Vegetative 50-60% is ideal because it keeps them from transpiring and dehydrating. More can cause wilting and mold, less can cause wilting and dehydration. During flower 30-40%. This is to prevent mold but also to simulate the dry cool air of fall and winter so the buds produce more resin and ripen.
Welcome to the forum @brucealmighty
Humidity and temp are both important and closely related as well as the each affect the other. Here is a VPD chart to help you out. VPD is something you should learn about and how it affects your plants transpiration.
And that’s a beautiful set up you got there. Keep us updated on the grow.
That chart just confuses me. What is the purpose of the chart I know it’s VPD or whatever but what is that and how do I read that chart? So if I’m running a plant 72 degrees 36% humidity It says that I’m between 1.03and 1.14 If I’m reading that right that’s not too bad correct? they are 5 weeks from flip and probably three weeks from flowering start.
@dmtscravey with this chart you want to be in the green, blue, and purple zones. The red zones can effect growth negatively. So yeah 72 degrees F at 36% humidity during flower is in the healthy ranges.
I have been running from 31% to 33% so it looks like I will be investing in a humidifier it shouldn’t take a very large unit for a grow tent. Thanks for all the information
@brucealmighty a couple tips on your humidifier. Get a true ultrasonic one, not one that uses a wick. Make sure to part that hold water is light proof, or you will grow algae. Use CLEAN water, the cleaner/purer it is the less you have to clean/decalcify it. Dont let it blow directly on the plants.
Having said all that serious stuff, theres a really cool green frog humidifier that fits the bill perfectly and it’s a FROG. Someone on here has one in their room. It may be smaller but is a FROG.
frog humidifier $11.99 at Manards sounds cheap enough
